Abstract: For closing gaps between blocks of a moving edge dam prior to its travelling downstream into the entrance of a moving mold defined between upper and lower revolving casting belts moving downstream from the mold entrance to its exit, the moving edge dam is initially elevated into a crest, as shown in FIGS. 12 and 14. This crest is above a plane generally defined by the lower casting belt travelling downstream. Then, a guide roller positioned above thrusts downwardly upon the moving edge dam bending it convex downwardly as shown at "B" in FIG. 14 for causing its dam blocks to press against each other for sliding them along their high strength endless flexibile carrying member, thereby closing gaps between the blocks entering the mold entrance for sealing the entrance against outward leakage of molten metal between blocks.

Abstract: A game of manual dexterity and skill utilizes a game apparatus comprising a thin elongated flexible cord and a plurality of disks each having a central opening therein loosely accommodated on the flexible cord, with a stop member preventing the disk from sliding off. A variety of play patterns may be established by manipulating the game apparatus to separate the disks and revolve the disks in generally circular paths.
